How are the heights measured?
All tree, and nothin' but the tree! We measure from the top of the soil to the top of the tree; the height of the container or the root system is never included in our measurements.
What is a gallon container?
Nursery containers come in a variety of different sizes, and old-school nursery slang has stuck. While the industry-standard terminology is to call the sizes "Gallon Containers", that doesn't exactly translate to the traditional liquid "gallon" size we think of. You'll find we carry young 1-gallons, up to more mature 7-gallons ranging anywhere from 6 inches to 6ft.
How does the delivery process work?
All of our orders ship via FedEx Ground! Once your order is placed online, our magic elves get right to work picking, staging, boxing and shipping your trees. Orders typically ship out within 2 business days. You will receive email notifications along the way on the progress of your order, as well as tracking information to track your plants all the way to their new home!
Why are some states excluded from shipping?
The short & sweet answer is: "United States Department of Agriculture Restrictions." Every state has their own unique USDA restrictions on which plants they allow to come into their state. While we wish we could serve everyone, it's for the safety of native species and helps prevent the spread of invasive disease & pests. We've gotta protect good ole' Mother Nature, after all.

There is no question that barberries are excellent shrubs, among the toughest and most reliable garden plants there are. The red-leaf varieties in particular are incredibly valued for their unique coloring. In recent years, though, their reputation has been tarnished by growing concerns over their ability to spread through seed into natural areas, threatening complex ecosystems and reducing the diversity of local environments. As so often happens at those times, professional horticulturists set to work to solve the problem. After 10 years of trials and testing, we can now offer you the results – the first red-leaf sterile variety, the amazing Sunjoy Mini Maroon® Barberry. This is not some marketing hype either, but supported by extensive testing and trials. These plants are not only compact, dark-red all season, and tough, they are 98.8% to 100% sterile – they produce no seeds, so no spreading into surrounding natural areas. Problem solved, and you can plant freely, knowing that you are doing nothing harmful to your local environment.
Growing the Sunjoy Mini Maroon® Barberry
Size and Appearance
The Sunjoy Mini Maroon® Barberry is a compact deciduous shrub, growing 3 or 4 inches a year, and producing a bushy, dense shrub with many branches, growing 2 to 3 feet tall and wide. The stems are flexible and strong, never breaking under snow. The leaves grow evenly along young stems, and in clusters on older ones, keeping bushes dense, with leaves throughout their branches. The leaves are smooth and rounded ovals, up to 1 inch long, and from the time they first emerge, until the drop in fall they maintain a rich, dark maroon-purple coloring, with no greening during the summer months, even in hot areas. At the base of each leaf cluster is a short, sharp spine, which makes a row of barberry virtually impenetrable to four or two-legged intruders.
In spring, while the new leaves are still small, clusters of 3 to 8 bright-yellow flowers form all along the stems. A single bush can carry 1,000 of these bright blossoms, and they add a cheerful and colorful touch, nestling among the purple leaves, for about 2 weeks. In ordinary barberry, these blooms would develop into seed-filled red fruits, but in this specially-bred barberry fruits are almost never produced, and any that are while lack viable seeds.
Using the Sunjoy Mini Maroon® Barberry in Your Garden
This great compact little shrub is perfect for planting in the front of your shrub beds. With leaves right to the ground it fills spaces all by itself. Plant it alone, in clusters or in rows as edging. Space grouped plants up to 18 inches apart for a solid drift of purple, or a great informal hedge that needs no clipping. You can also trim established hedges once a year for a super-neat look. Plant it on slopes, in the narrow beds of terraced walls, among rocks, and anywhere where you want bright color. It can also be used in planters and pots. It contrasts well with other barberry bushes – those with golden foliage, for example.
Very resistant to cold, yet also enjoying lots of sun and heat, the Sunjoy Mini Maroon® Barberry is completely hardy all the way from zone 4 to zone 8. Plants in boxes and pots can be left outdoors all year round in zones 6, 7 and 8. In colder zones, bury pots or remove the plants and place them temporarily in garden beds.
Sun Exposure and Soil Conditions
Full sun is needed by the Sunjoy Mini Maroon® Barberry to keep it vigorous and to keep the foliage color at its brightest. More than an hour or two of shade each day is not desirable. As for soil, any well-drained earth, including drier sands and gravels, as well as clays and urban soils, are suitable – just avoid wet areas.
Maintenance and Pruning
The Sunjoy Mini Maroon® Barberry is untroubled by pests or diseases, and left alone by deer and rabbits, who are repelled by the spiny stems. This plant remains neat and compact, really not needing any trimming at all. If you want to keep a very neat hedge, trim in early spring, just before the new leaves emerge. Even in fall, when the leaves fall, they are small and just disappear – nothing to rake.
History and Origin of the Sunjoy Mini Maroon® Barberry
Barberry, Berberis thunbergii, has been grown in our gardens since it was first introduced in 1875 from Japan by plant collectors with the Arnold Arboretum in Boston. Those first plants were tall, with green leaves, but popular for their yellow flowers and red berries. The first purple-leaf forms appeared in France before 1900. Since then purple-leaf forms have been always the most popular, so it was natural for Dr. Thomas Ranney, of North Carolina State University in Raleigh, to launch his quest for seedless barberry plants with plants of that color. He began in 2005 by crossing together two different seedlings of Berberis thunbergii var. atropurpurea, the ‘natural’ purple-leaf form. To improve the chances of growing unique plants, he treated the seeds with ethyl methanesulfonate, a chemical that accelerates the number of changes when cells divide. He sprouted the seeds, and from among the seedlings he selected one for further study. After extensive trials and tests, he knew he had a compact, bushy plant with excellent foliage color, but one that wouldn’t produce seeds. Careful tests showed it was 98.8% to 100% sterile. He named it ‘NCBT1’ and received a patent for it, to benefit the University, in 2019. It was released the same year by Spring Meadows Nurseries, as part of their Proven Winners® range. They registered the trademark name, Sunjoy Mini Maroon®, for it, adding it to their SUNJOY® range of exciting, colorful barberry bushes.
